I've tried pinning the media type at the switch it is plugged into thinking perhaps it's fighting with the switch it's connected to, but that's not it -- it makes no difference. Nor does it appear to be traffic related. The flapping hoses the snmp daemon that is running on the machine, causing it to "go deaf." Interestingly enough it doesn't interrupt a ssh session that you may have open if/when it happens. Any ideas on how I can figure out why (e.g. what condition the interface code is seeing?) the interfaces are resetting? This is all I have in the dmesg. --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/ --------------ms070509000200030302030701 Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIIGXzCC BlswggRDoAMCAQICASkwDQYJKoZIhvcNAQELBQAwgZAxCzAJBgNVBAYTAlVTMRAwDgYDVQQI EwdGbG9yaWRhMRIwEAYDVQQHEwlOaWNldmlsbGUxGTAXBgNVBAoTEEN1ZGEgU3lzdGVtcyBM TEMxHDAaBgNVBAMTE0N1ZGEgU3lzdGVtcyBMTEMgQ0ExIjAgBgkqhkiG9w0BCQEWE0N1ZGEg U3lzdGVtcyBMTEMgQ0EwHhcNMTUwNDIxMDIyMTU5WhcNMjAwNDE5MDIyMTU5WjBaMQswCQYD VQQGEwJVUzEQMA4GA1UECBMHRmxvcmlkYTEZMBcGA1UEChMQQ3VkYSBTeXN0ZW1zIExMQzEe MBwGA1UEAxMVS2FybCBEZW5uaW5nZXIgKE9DU1ApMIICIjANBgkqhkiG9w0BAQEFAAOCAg8A MIICCgKCAgEAuYRY+EB2mGtZ3grlVO8TmnEvduVFA/IYXcCmNSOC1q+pTVjylsjcHKBcOPb9 TP1KLxdWP+Q1soSORGHlKw2/HcVzShDW5WPIKrvML+Ry0XvIvNBu9adTiCsA9nci4Cnf98XE hVpenER0qbJkBUOGT1rP4iAcfjet0lEgzPEnm+pAxv6fYSNp1WqIY9u0b1pkQiaWrt8hgNOc rJOiLbc8CeQ/DBP6rUiQjYNO9/aPNauEtHkNNfR9RgLSfGUdZuOCmJqnIla1HsrZhA5p69Bv /e832BKiNPaH5wF6btAiPpTr2sRhwQO8/IIxcRX1Vxd1yZbjYtJGw+9lwEcWRYAmoxkzKLPi S6Zo/6z5wgNpeK1H+zOioMoZIczgI8BlX1iHxqy/FAvm4PHPnC8s+BLnJLwr+jvMNHm82QwL J9hC5Ho8AnFU6TkCuq+P2V8/clJVqnBuvTUKhYMGSm4mUp+lAgR4L+lwIEqSeWVsxirIcE7Z OKkvI7k5x3WeE3+c6w74L6PfWVAd84xFlo9DKRdU9YbkFuFZPu21fi/LmE5brImB5P+jdqnK eWnVwRq+RBFLy4kehCzMXooitAwgP8l/JJa9VDiSyd/PAHaVGiat2vCdDh4b8cFL7SV6jPA4 k0MgGUA/6Et7wDmhZmCigggr9K6VQCx8jpKB3x1NlNNiaWECAwEAAaOB9DCB8TA3BggrBgEF BQcBAQQrMCkwJwYIKwYBBQUHMAGGG2h0dHA6Ly9jdWRhc3lzdGVtcy5uZXQ6ODg4ODAJBgNV HRMEAjAAMBEGCWCGSAGG+EIBAQQEAwIFoDALBgNVHQ8EBAMCBeAwLAYJYIZIAYb4QgENBB8W HU9wZW5TU0wgR2VuZXJhdGVkIENlcnRpZmljYXRlMB0GA1UdDgQWBBTFHJQt6cloXBdG1Pv1 o2YgH+7lWTAfBgNVHSMEGDAWgBQkcZudhX383d29sMqSlAOh+tNtNTAdBgNVHREEFjAUgRJr YXJsQGRlbm5pbmdlci5uZXQwDQYJKoZIhvcNAQELBQADggIBAE9/dxi2YqjCYYhiybp4GKcm 7tBVa/GLW+qcHPcoT4dqmqghlLz8+iUH+HCJjRQATVGyMEnvISOKFVHC6aZIG+Sg7J8bfS4+ fjKDi9smRH2VPPx3bV8+yFYRNroMGHaPHZB/Xctmmvc+PZ9O2W7rExgrODtxIOB3Zs6wkYf+ ty+9r1KmTHlV+rRHI6timH1uiyFE3cPi1taAEBxf0851cJV8k40PGF8G48ewnq8SY9sCf5cv liXbpdgU+I4ND5BuTjg63WS32zuhLd1VSuH3ZC/QbcncMX5W3oLXmcQP5/5uTiBJy74kdPtG MSZ9rXwZPwNxP/8PXMSR7ViaFvjUkf4bJlyENFa2PGxLk4EUzOuO7t3brjMlQW1fuInfG+ko 3tVxko20Hp0tKGPe/9cOxBVBZeZH/VgpZn3cLculGzZjmdh2fqAQ6kv9Z9AVOG1+dq0c1zt8 2zm+Oi1pikGXkfz5UJq60psY6zbX25BuEZkthO/qiS4pxjxb7gQkS0rTEHTy+qv0l3QVL0wa NAT74Zaj7l5DEW3qdQQ0dtVieyvptg9CxkfQJE3JyBMb0zBj9Qhc5/hbTfhSlHzZMEbUuIyx h9vxqFAmGzfB1/WfOKkiNHChkpPW8ZeH9yPeDBKvrgZ96dREHFoVkDk7Vpw5lSM+tFOfdyLg xxhb/RZVUDeUMYIE4zCCBN8CAQEwgZYwgZAxCzAJBgNVBAYTAlVTMRAwDgYDVQQIEwdGbG9y aWRhMRIwEAYDVQQHEwlOaWNldmlsbGUxGTAXBgNVBAoTEEN1ZGEgU3lzdGVtcyBMTEMxHDAa BgNVBAMTE0N1ZGEgU3lzdGVtcyBMTEMgQ0ExIjAgBgkqhkiG9w0BCQEWE0N1ZGEgU3lzdGVt cyBMTEMgQ0ECASkwCQYFKw4DAhoFAKCCAiEwGAYJKoZIhvcNAQkDMQsGCSqGSIb3DQEHATAc BgkqhkiG9w0BCQUxDxcNMTUwODIwMTg1MDM1WjAjBgkqhkiG9w0BCQQxFgQUMoaXzLIHvOTk r3NCxjUVBeZQ/5AwbAYJKoZIhvcNAQkPMV8wXTALBglghkgBZQMEASowCwYJYIZIAWUDBAEC MAoGCCqGSIb3DQMHMA4GCCqGSIb3DQMCAgIAgDANBggqhkiG9w0DAgIBQDAHBgUrDgMCBzAN BggqhkiG9w0DAgIBKDCBpwYJKwYBBAGCNxAEMYGZMIGWMIGQMQswCQYDVQQGEwJVUzEQMA4G A1UECBMHRmxvcmlkYTESMBAGA1UEBxMJTmljZXZpbGxlMRkwFwYDVQQKExBDdWRhIFN5c3Rl bXMgTExDMRwwGgYDVQQDExNDdWRhIFN5c3RlbXMgTExDIENBMSIwIAYJKoZIhvcNAQkBFhND dWRhIFN5c3RlbXMgTExDIENBAgEpMIGpBgsqhkiG9w0BCRACCzGBmaCBljCBkDELMAkGA1UE BhMCVVMxEDAOBgNVBAgTB0Zsb3JpZGExEjAQBgNVBAcTCU5pY2V2aWxsZTEZMBcGA1UEChMQ Q3VkYSBTeXN0ZW1zIExMQzEcMBoGA1UEAxMTQ3VkYSBTeXN0ZW1zIExMQyBDQTEiMCAGCSqG SIb3DQEJARYTQ3VkYSBTeXN0ZW1zIExMQyBDQQIBKTANBgkqhkiG9w0BAQEFAASCAgAh+n7/ dZBPvHeVr2mr3cQyQV7+labXiszP1ra5qh3s4lKG5qWecS92Zp82D4AjoYgJrz6coC48nIS6 oiTVti+m1XQX0sb7oNwQ+ZCWwUNXcrTvjnQeT3VaeiVKBeIVQyT4Ku+rr/HrUdbH/17nCN/9 xN4/ZQlnDhMIOlCKMAE+KXl0VAPUcWAquwk7wu6LCIELxzV9odD1dKbO9kLrdujnDD+ONv7N s3I1uypkQwATKcewD51Ys5aFQgoWVn3pzrtXZ0yiVf6vRATkhXTaIILm/yGpoaSuio9kyBx4 zMGE01mxuPBWvVa4O2Qu4ZZtV8eH7o1S34b1kiXN/YqoYFYvMqNyFXGDKtaX6Px03Kuj2zkV ZhY+bJOHWJrdmJ+nl4SjlOY9TBzFYA17Oe7tlYylu3T4ayJmKlkRkOgL/i0WOcjT5VbkWR5O LRqE2Dnv4hsZ1db5XilXJkT6KKDRgz0bhO8R/37J19oNLjdd7VILUqy+zhAx4ZOqKYJg/+ZP GAV15Ckdby6CBDEQ46QbXZ/kmgIDxn9ee4n/EWI664TsQYTx3+zjDLSjZkQlNw/oYSODmLCX Nim3dn/i0svsRaTZtq0Qtp0rNRTsj0szcETjPzDnFc3usk/424nxkyraLt4HCaw58uIYQAUF uqLE8aTLhwjVRUfh5nWCF6enGe/NsQAAAAAAAA== --------------ms070509000200030302030701--
